Objective To observe the effect of acupuncture and massage on tiptoe in children with spastic cerebral palsy. Methods 49 children with spastic cerebral palsy were divided into treatment group (n=24) and control group (n=25) in accordance with the order of visiting. The control group accepted routine rehabilitation, and the treatment group accepted acupuncture and massage in addition. They were assessed with Composite Spasticity Scale (CSS), the angle of ankle passive dorsiflexion before and after treatment. Results The scores of CSS and the angle of ankle passive dorsiflexion improved in both groups after treatment (P<0.001), and improved more in the treatment group than in the control group (P<0.001). The rate of improvement was 95.6% in the treatment group, and 78.26% in the control group (P<0.05). Conclusion Acupuncture and massage may further improve the correcting of the tiptoe in children with spastic cerebral palsy.

OBJECTIVETo study the influence of bone marrow mesenchymal stem cells (MSCs) transplantation on hypoxic pulmonary hypertension (HPH) in rats.

METHODSSD rats MSCs were separated, cultivated, identified and labeled by the green fluorescence protein (GFP) gene virus and transplanted in vitro. Healthy male SD rats were randomly divided into four groups: Normal control group (NC group) and HPH group (eight rats respectively), HPH+ MSCs transplantation group and HPH+ VEGF+ MSCs transplantation group (twenty-four respectively). The test employed atmospheric intermittent low oxygen method to establish the rat model of pulmonary hypertension and stem cells were transferred and transplanted. The rats' mean pulmonary artery pressure (mPAP) was observed; right ventricular hypertrophy index (RVHI) was calculated; the morphological change of lung small artery in various groups of rats was observed under the microscope; the distribution of lung small artery and adenovirus transfection fluorescently labeled MSCs was observed under a fluorescent microscope after 7, 14 and 28 days when stem cell was transplanted.

RESULTSFor NC group, the mPAP (mmHg) was 15.5 +/- 1.5 after twenty-eight days while the mPAPs for HPH , MSCs and MSCs+ VEGF were 26.1 +/- 1.9, 21.6 +/- 2.7 and 20.1 +/- 2.9 respectively which were apparently higher than that of NC group (P < 0.01) and compared with HPH group (P < 0.01), which declined clearly. There was no significant difference between MSCs and MSCs+ VEGF. After twenty-eight days, RVHI for NC group was 0.28 +/- 0.02 while the RVHI for HPH, MSCs and MSCs + VEGF were 0.43 +/- 0.07, 0.34 +/- 0.03 and 0.35 +/- 0.01 respectively which was apparently higher than that of NC group (P < 0.01) but which was clearly lower than that of MSCs and MSCs+ VEGF (P < 0.05) and there was no significant difference between MSCs and MSCs + VEGF. For HPH group, pulmonary arteriole wall became apparently thicker, the lumen became significantly narrow and nearly obstructed after twenty-eight days, the endothelial cells were incomplete; compared with HPH group, pulmonary arteriole wall of MSCs group became thin, the lumen was smooth and the completeness of endothelial cells was improved. Whereas for MSCs and MSCs + VEGF, these changes were not significantly clear.

CONCLUSIONAfter MSCs transplantation, mPAP and RVHI decline sharply and lung small artery remodeling is improved which partially reverses HPH process; there is no significant difference between VEGF together with MSCs transplantation group and pure MSCs.

To examine the relationship between genetic variants in the interleukin-6 receptor gene and obesity. The result showed that the carriers of Asp358 homozygotes had higher risk in developing obesity when compared with Ala358 homozygotes (OR = 1.32,95% CI 1.07-1.68, P = 0. 041). Interleukin-6 receptor gene pulymorphism was significantly associated with obesity.

While the medicine pattern of biomedicine turn to biological-psychology-society, the medical trouble communication becomes more and more important in the medical service. Good medical trouble communication ability is the essential condition of doctor. As oral cavity clinicians, only by gasping the principle of communication can we appropriately utilize some skills of communication exchange,establish the good medical trouble relations with the patient and achieve the good treatment result finally.

This study was based on live yeast cell derivative (LYCD), which was produced by live yeast cell stressed with high temperature and H 2O 2. The results showed that pretreating of low dose(37℃and 0.2mmol/L H 2O 2) could increase the content of GSH and the activity of SOD and CAT. These pretreatment could induce the resistance to lethal concentration of H 2O 2. LYCD was produced by yeast treated with 37℃ and 0.2mmol/L H 2O 2. And it was found that the survival of yeast treated with lethal concentration of H 2O 2 obviously increased, while LYCD was added in yeast culture. It indicated that LYCD could have resistance to oxidative condition.

Objective To investigated the expression of intracellular adhesion molecule-1 (ICAM-1)in mouse to rat cardiac xenograft and the effects of leflunomide and cyclosporine.Methods NIH mice and Wistar rats served as donors and recipients respectively.Mouse to rat heterotopic heart transplantation was performed(in the neck).The experiments were divided into 4 groups:CsA group,leflunomide(Lef)group,CsA+Lef group,control group.It was the time of rejection that no pulsation could be detected in the transplanted heart.The expression of ICAM-1 protein in cardiac xenograft tissue was detected by immunohistochemistry and Western blot in each group.Results The survival time of cardiac xenograft in control group,CsA group,Lef group and CsA+Lef group was (2.17?0.41),(2.50?1.05),(4.17?1.33)and(6.50?2.56)days respectively.The expression of ICAM-1 protein(IOD)in cardiac xenograft tissue in control group,CsA group,Lef group and CsA+ Lef group was 155.40?5.33,150.73?5.13,104.65?6.15 and 29.24?2.76 respectively.Conclu- sion The expression of ICAM-1 protein was strong in mouse to rat cardiac xenograft.The combined use of Lef and CsA can significantly suppress the expression of ICAM-1 protein in the cardiac xenograft.
